Acoustic Power Recovery System for Thermoacoustic Cooling

Schwartz D.E., Garner S.R., Johnson J.R., Tuganov A.V., Palo Alto Research Center, US

In this work, we present a novel zero global-warming-potential, high efficiency thermoacoustic heat pump that can replace vapor compression systems for conventional air conditioning and refrigeration.

Technologies for Deep Reductions in Military Operational Energy Use

Brown R., Sharp T., Lindsey M., Kiser S., Andrews K., Lawrence Berkeley National Laboratory, US

The U.S. Pacific Command (PACOM) has begun a research program for Transformative Reductions in Operational Energy Consumption (TROPEC), which will identify, refine and validate technologies for reducing energy use in expeditionary military outposts. The primary [...]

Performance and Potential Applications of Direct Expansion Ground Source Heat Pump systems for Building Energy

Omer A.M., University of Nottingham, UK

In the recent attempts to stimulate alternative energy sources for heating and cooling of buildings, emphasise has been put on utilisation of the ambient energy from ground source and other renewable energy sources. Exploitation of [...]

Sodium Clusters for a Superior Light Source

Gokturk H., Ecoken, US

Sodium lamp is one of the most efficient light sources providing an output of 150-200 lumens/watt; for comparison, light output of a fluorescent lamp is about 60-100 lumens/watt. Despite its efficient operation, sodium lamp is [...]
